The two makes are almost identical however there may be some minor differences In moulding etc between the two.Main Picture shows the Goflex & the Technical drawing shows the Alca.*(Diameter's quoted (32,40 & 50mm) are actual sizes**. Some other suppliers use slightly smaller or larger fittings but may still refer to them as 32,40 or 50 mm so it is recommended that to be certain your fittings are compatible you measure the internal diameter of your fittings to ensure a suitable seal / Fitting will be achieved.*(Some solvent pipes use a larger pipe diameter so measure your pipe and fittings diameters to ensure correct sizing is used. Ours is quoted in actual sizes** i.e 40 mm is 40 mm. Also note sometimes the addition of extra glue can resolve small tolerance differences. **(+/- some small acceptable tolerance) British Standard Pipe Thread is a family of standard screw thread types that has been adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.A list of 16 thread sizes are defined by the standards, ranging from 1?16 Inch to 6 Inch. The size was originally based on the inner diameter measured in inches of a steel tube for which the thread was intended. This often causes confusion, as people think the size refers to the outside diameter of the male thread. ## Features - Universal Flexible Waste pipe or Trap - Complete with rubber seal - 1 1/2 BSTP - No Cutting - Flexible to fit many situations - Usually for a Sink or Bath ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00XGWVQM0 | | Best Sellers Rank | 47,712 in DIY & Tools ( See Top 100 in DIY & Tools ) 55 in Traps | | Brand | WITPOCE | | Colour | White | | Customer Reviews | 4.1 4.1 out of 5 stars (575) | | Item Length | 3.81 Centimetres | | Item Weight | 108 Grams | | Manufacturer | GoPlaST / ALCA | | Material | Alloy Steel, Plastic, Rubber | | Nominal Wall Thickness | 7.2 millimeters | | Outside Diameter | 1.88 Millimetres | | Unit Count | 1.0 count | ## Product Details - **Brand:** WITPOCE - **Colour:** White - **Item length:** 3.81 Centimetres - **Item weight:** 108 Grams - **Manufacturer:** GoPlaST / ALCA - **Material:** Alloy Steel, Plastic, Rubber - **Nominal wall thickness:** 7.2 millimeters - **Number of Packs:** 1 - **Outside diameter:** 1.88 Millimetres - **Unit count:** 1.0 count ## Images ![Waste Trap 1 1/2'' to 40/50mm - Universal - Flexi Waste - Bath - Sink - Flexible Pipe Connector - Image 1](https://m.media-amazon.com/images/I/31bzp1Y69bL.jpg) ## Questions & Answers **Q: looking for a waste pipe flexible 50mm screw side and 40mm push fit other end** A: Hello, The screw part for this (Waste Trap 1 1/2'' to 40/50mm) has approx outside thread diameter of 47.80 mm.
